They are less researched but there is evidence in support of SJW that I posted. SJW needs to be discussed with the pdoc, I believe, because it has known drug interactions. But yourquestion vannot be answered in full due to fewer studies of herbs and supplements. There is good though not thoroghly conclusive evidence in support of fish oil for moods on general, and since fish oil is cheap and helps other organs of the body, why not take it? If depression is associated with and sometimes even caused by anemia, iron supplementation is recommended. Vit D helps some people. Vit D is helpful in general, for general health and disease prevention, so sure why not. And some people take more complex supplements.
